== Gtk::TreeViewColumn and Gtk::CellRenderer
-The Gtk::TreeViewColumn object is a visible column in a Gtk::TreeView widget. It determines the geometry, type. As mentioned earlier, a tree view displays one or more Gtk::TreeViewColumn objects. Tree columns are composed of a header and the cells of data that are organized as one column. Each tree view column also contains one or more visible columns of data. For instance, in a file browser, a tree view column may contain one column of "icon file images" and one column of "file names". The header of the Gtk::TreeViewColumn object contains a title that describes what data is held in the cells below. If you make the column sortable, the rows will be sorted when one of the column headers is clicked. Gtk::TreeViewColumn objects actually do not render anything to the screen. This is done with an object derived from the Gtk::CellRenderer.

The Gtk::CellRenderer is an abstract base class of a set of objects used for rendering a cell to a Gdk::Drawable. These objects are used primarily by the Gtk::TreeView widget, though they aren't tied to them in any specific way. As already mentioned, it is worth noting that Gtk::CellRenderer is not a Gtk::Widget and cannot be treated as such.
